The answer depends on the units used for 30 and 50. What are they? inches? miles? Since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
If the numbers represent feet, and you are talking about a rectangle, you simply multiply length x width.
To find the square footage of a rectangular area, you multiply the length by the width. In this case, the area measuring 50 feet by 30 feet would have a square footage of 1,500 square feet (50 x 30 = 1,500).
50*50 = 2500 square feet
150 x 50 = 7,500 square feet.
13.8 square feet
30 ft. x 50 ft. = 1500 sq. ft. = 1500/9 sq. yd. = 166 2/3 sq. yd.
30" x 50" = about 1.042 square feet.
50' x 10' x 30' = 15,000 (square feet) = 0.344352617 acres.
Answer = 50 x 50 = 2500 sq feet
50 acres = 2,178,000 square feet.
50 square meters = ~538.2 (538.195521) square feet.
To find the square footage of a rectangular area, you multiply the length by the width. In this case, the area measuring 50 feet by 30 feet would have a square footage of 1,500 square feet (50 x 30 = 1,500).
You have to multiply the two dimensions to get the area. In this case the answer will be 1,500 square feet.
50*50 = 2500 square feet
150 x 50 = 7,500 square feet.
There are 538 square feet in 50 square meters.
50 square meters = ~538.2 (538.195521) square feet.
11" by 50' is 45.83 square feet.
